6 Claims.

more fully described and claimed which is simple in structure consisting of the fewest number of parts, thereby assuring positive and accurate operation for whatever purpose the device is Other objects will appear hereinafter.

YThe invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying` drawing showing the preferred form of construction, and in which:

Fig.` 1 is a sectional elevational view of the invention;

Fig. 2 is a sectional detail View of the same taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is a sectional detail view of the same taken substantially on line 3 3 of Fig. 1;

Fig. 4 is a sectional detail view of the same taken substantially on line 4-4 of Fig. 1;

Fig. 5 is a diagrammatic view illustrating a typical circuit arrangement with which the invention is adapted to be associated; and

Fig. 6 is a perspective View of a device to illustrate the operation of the. present invention therewith.

Referring more particularly to the drawing illustrating the preferred form of construction, a supporting structure is indicated at I0. This structure includes an elongated plate having at opposite ends thereof angled end portions |2. This plate is mounted upon a base plate I3, and associated with this base plate I3 at opposite ends thereof are bracket elements |4 to which is secured, as at I5, an attaching plate IS bent to provide extended portions II for connection in a suitable stationary support or unit I8, as at I9.

The angled end portions I2 of the plate I I adjacent their upper end portions are provided with aligned slots 20 communicating with enlarged openings 2|. Slidably arranged through the enlarged openings 2|, with the longitudinal edge portions 22 thereof riding in the slots 2|, is a movable supporting bar 23, one end of which is angled, as at 24. Secured to this angled end 24, as at 25, is one end portion of a retraction spring 26, the said spring 26 projecting through openings 21 formed in the end portions |2 inwardly of the openings 2|, and the opposite end portion of this spring 2B is connected, as at 28, to the adjacent end portion I2 of the end portions I2.

The bar 23 is provided with a plurality of alternately disposed teeth 29 and 29 preferably, though not necessarily provided by being struck fromthe body of the bar 23.

Mounted upon the plate I9, as at 30. is a bracket supporting a magnetic coil 3|. This coil 3| is connected in circuit with a source of elec- `tric energy through the mediiun of conductors 32,

and is controlled by a switch 43 which may be either manually or electrically operated. The magnetic coil 3| includes a spring-controlled are mature 33, and this armature has secured thereto a keeper plate This keeper plate is provided with an elongated slot 35 to provide oppostely disposed iianges 5l adapted to alternately engage the -teeth 29 of the bar 23, whereby when the armature is actuated by the coil 3| by virtue of its alternate engagement with the teeth 29 will permit an intermediate movement of the bar 29 during the time that the coil 3l is energized to actuate the armature 33.

On this bar 23 is secured a contact iinger 3S having means, as at 3'I, for connection with a conductor wire 38 leading from one side 39 of a source of electric energy 49. This finger 35 is adapted to successively engage contacts 4| secured to and supported by a non-conductive bar 42, in turn supported from the supporting structure i0 by means of the brackets I4.

The device thus described is capable of many usages, and therefore I do not desire to limit myself to any one particular use. For the purn pose of explaining the present invention, I have illustrated o-ne of the many usages to which the device constituting my invention may be applied.

In this instance, referring particularly to Figs. 5 and 6, 44 indicates a score board having sight openings 45 adapted to have displayed therein a score indicator 49 normally held from score indicating position by means of a latch structure including a keeper 4T and a pin 48. The keeper 4l is actuated through the medium of an armature 49 of a magnetic coil 59. This armature 49 is supported by a bracket 5| from a suitable stationary structure or unit 52.

The arrangement is such that when the coil 50 is energized, the armature is attracted thereby, and when thus attracted, the pivotal movement of this armature will pivot downwardly carrying therewith the keeper 4l from latched engagement with the pin 43, thus permitting the score indicator 49 to drop into position in the sight opening 45, it being understood that these score indicators are moved from position in the sight openings 45 by any approved or conventional means, the same not constituting a part of this invention.

The magnetic coils 50 are each connected to one side of the source of electric energy 40. The other side of these coils 50 are each connected to one of the contact members 4|. The arrangement is such that movement of the Contact finger 36 by the step-up action of the keeper plate 34 will successively energize the coils 50 to permit the score indicators 46 to move into score indicating position in the sight openings 45.

After the bar 23 has been permitted by action of the magnetic coil 3| and keeper plate 34 to move in its extreme position by the action of the spring 26, it is moved into retracting position, that is, its initial position, by suitable means, such as, for example, the hand manipulated finger 53 mounted on a slidable plate 54 slidably guided relative to the structure I8 by suitable guide channels 55, there being associated with this plate 54 a finger gripping portion 56 for the purposes of manipulating the plate 54 to retract the bar 23 to its initial starting position.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:
